Build character. Seek to be a better person tomorrow than you are today. Deliberately think about how you relate to yourself and those around you and make changes to attitudes and actions that need adjustment. Value the feedback of others on your journey to become a better you.
You always have a choice to change. You are a leader who can deal with outbursts of irritation or lack of empathy as decisively as you can change a direction for your company. Regularly reintroduce the new, improved you. You will get more from yourself and from those who look to you for leadership.
